The general purpose 1503C Portable MTDR Cable Tester generates a 1/2 sine pulse, with selectable pulse widths of 2, 10, 100, or 1000 ns. The high-resolution 2 ns pulse permits the identification of multiple faults as close together as one foot. The 1000 ns pulse gives the 1503C a range of 5,000 to 50,000 feet (depending on cable type and condition). The ultra-high-resolution 1503C generates a 200 ps rise time step pulse and has an output impedance of 50-ohms. The fast rise time permits the identification of multiple faults as close together as 0.6 inches. For most TDR applications, where determining distance to an impedance change is the key measurement, the 1503C is the best choice.
